"[T]he social forces that brought [New York City Mayor Bill] de Blasio to office are real," according to an article by Edward L. Glaeser in the Autumn 2015 special issue of City Journal, celebrating its 25th anniversary. "New York is indeed a highly unequal city, and it is filled with liberal voters, many of them young. The memories of the city's brush with bankruptcy and once-stratospheric crime rates are no longer keen.

"Thus, a meaningful center-right alternative to the new urban progressivism -- a force not just in New York but also in many other American cities -- must show how it can do more to fight poverty and promote economic mobility than can any liberal fix," Glaeser continues in "A New Opportunity Agenda."

"This next urban agenda, which respects and draws on the power of free people and free markets," according to Glaeser, "should seek to empower urban entrepreneurialism, build a competitive and regularly assessed urban education system, and unleash a vibrant market for labor and housing. Cities can lead the fight for economic opportunity but only if they're places of private entrepreneurship and public innovation, not battlegrounds for class warfare."
